The Stephenson Avenue Extension will provide a new connection from Cedric Street to Scarborough Beach Road, including an interchange at Mitchell Freeway.
Phase one phase was delivered by the City of Stirling and opened in February 2022. This included the extension of Scarborough Beach Road to Flax Way, new local road connections and improved shared paths.
Phase two is underway and will further extend Stephenson Avenue to Cedric Street. This will include a new grade-separated interchange with Mitchell Freeway with a southbound Smart Freeway on-ramp to replace the existing Cedric Street interchange, and local road links to Ellen Stirling Boulevard.
Significant upgrades to the shared path network along Stephenson Avenue are also underway. When complete, it will provide an uninterrupted path for PSP users in Perth's northern suburbs.
The Stephenson Avenue Interchange, shared path network and PSP infrastructure will begin to open in stages through late-2025.
The Stirling Bus Interchange will be delivered as part of this project, with completion anticipated in early-2026. Works are underway to increase capacity from a 16-stand to a 29-stand facility, with a new pedestrian access between Stirling Station and the southern car park. Main Roads WA are delivering this upgrade on behalf of the Public Transport Authority.
